At the heart of every KRASH ‘Ready To Perform’ craft is our powerful, proprietary 997cc twin-cylinder 2-stroke engine, the KV997. The power-valve cylinder is constructed of A365 high-pressure cast aluminum and features 88mm cast iron sleeves. Wiseco forged pistons are driven by our 82mm stroke forged crankshaft fitted with ProX connecting rods. Prior to assembling the crankshaft, all pins and surfaces are nitrate treated for increased durability. Tunable wet exhaust system features oversized stainless steel expansion chamber and aluminum water box. Premium pre-mixed fuel is delivered by our dual 48mm ‘Black Ops’ carburetors, featuring Mikuni internals, through high-performance carbon fiber reeds. Combustion is controlled by our DC-CDI that is programmed with three preset maps that can take you from 70hp to 115hp to 130hp at the push of a button.
Want even more power? No problem! Swap out our 1.2kg aluminum charging flywheel for our 384gr aluminum total-loss flywheel and send it!
The KV997 Cylinder is made from A356 high pressure die cast aluminium and 88mm bored steel sleeves. It features 4 Auxiliary ports, 1 boost port, 2 Auxiliary exhaust ports and 1 main exhaust port per cylinder. The air and fuel are feed into the intake through the side of the cylinder at a 30 degree angle and wrap around the crank as the piston plunges from TDC to BDC. The cylinders are 150mm apart to increase the inner auxiliary ports area for improved bottom end punch.
The 4340 forged crankshaft weighs in at 7.8kg and gives the motor an 82mm stroke while being assembled using NSK C3 bearings. Our rods are 144mm long giving our engine an ideal rod to stroke ratio of 1.76. All pins and surfaces are nitrate treated for increased longevity.
The DC-CDI comes with 3 pre-set maps to take you from 70hp to 115hp to 130hp at the push of a button. The 7075-T6 flywheel weighs 1.2kg and faces away from the engine, with the pickup at the back of the flywheel. This enables the user to bolt on a 384 gram total-loss flywheel for more responsive power.
Our dual ‘Black Ops’ Carburetors stand 84mm tall, feature Mikuni internals and are complemented with individual air pods.
